Anchor xy_from_polar xy_from_polar
list of numbers xy_from_polar(magnitude: number, dir: number)
list of vectors xy_from_polar(magnitude: vector, dir: vector)
fieldset xy_from_polar(sp: fieldset, dir: fieldset)
Converts vector data from meteorological polar representation to xy representation. In polar representation the data is specified by two components:
magnitude
: represents the speed/magnitudedir
: represents the direction of the vector in degrees. Angles measured from South in clockwise direction.
In the target xy representation the x axis points East while the y axis points North.
The type of the result depends on the type of the input data
- if the input is
number
the result is a list of two numbers - if the input is
vector
the result is a list of two vectors, the first vector contains the x components while the second vector the y components - if the input is f
ieldset
the result is a fieldset where an x component field is immediately followed by the corresponding y component field.
